Five companies form a group. The sales of each company during the year ending 5 April, 1988, are shown in the table below. Company ABCDE Sales (in 1000s) 55 130 20 35 60 Draw a pie chart of radius 5 cm to illustrate this information. For the year ending 5 April, 1989, the total sales of the group increased by 20%, and this growth was maintained for the year ending 5 April, 1990. If pie charts were drawn to compare the total sales for each of these years with the total sales for the year ending 5 April, 1988, what would be the radius of each of these pie charts? If the sales of company E for the year ending Sth April, 1990, were again 60 000, what would be the angle of the sector representing them?
